HNTB is serving as project manager consultant on the mega Johnson County Gateway Interchange, the Kansas Department of Transportation’s largest and first-ever design-build project. The critical interchange project provides more efficient movement as commuters navigate changes between I-435, I-35 and Kansas Highway 10.

In the project’s early stages, HNTB assisted KDOT with initial conceptual planning and preliminary design, helped develop the state’s first design-build RFP and facilitated the procurement process.
